BACKGROUND

The present invention relates to systems and methods for portable snow footwear. In particular, the invention relates to portable, lightweight and collapsible stable snowshoes.

Modern conventional snowshoes are made from newer synthetic materials and, therefore, are lighter than older conventional wooden-framed snowshoes. However, these newer snowshoes are still somewhat bulky and hence for space utility reasons are often attached to the exterior of backpacks when not in use.

Thus, there is an urgent need in the cold-weather backpacking field to create new, useful, portable, stable and collapsible snowshoes. These improved collapsible snowshoes have to be strong, durable and lightweight, and well suited for use on rugged terrain often encountered outdoors in cold weather.

I. Collapsible Snowshoe Embodiments

FIGS. 1A-IC are a perspective view, an exploded view and a side view, respectively, illustrating one embodiment of a snowshoe 100 for travelling on snow fields. Snowshoe 100 includes a collapsible frame 110, a flexible webbing 120 and a shoe binding 130, coupled to each other to provide a substantially larger footprint for a suitable footwear such as a hiking boot (not shown). FIG. 1D is a side view of an alternate embodiment for snowshoe frame 110.

Webbing 120 includes front frame interface elements 128 a &128 b, side sleeves 125 a & 125 b, mating fasteners 124 a & 124 b, a rear strap 122 and a rear frame interface element 126.

The frame interface elements 128 a, 128 b and/or 126 may be machined, injection molded, or manufactured in any suitable fashion, and can also be made from metal, plastic, polycarbonate, or any other suitable material. In another variation, frame interface elements 128 a, 128 b and/or 126 are grommets or washers coupled to or sewn into the webbing 110 that slide over or otherwise couple to the respective ends of the collapsible frame 110.

In this embodiment, the frame interface elements 128 a, 128 b and 126 are pockets that are coupled to or sewn into the webbing 120 that slide over or otherwise couple to the respective ends of the collapsible frame 110. Hence, when assembled, front pockets 128 a & 128 b securely accommodate the respective front ends of frame 10, while the rear pocket 126 accommodates the rear ends of frame 110.

Mating fasteners 124 a & 124 b can be, for example, a quick release buckle set shown in FIG. 1B. Fasteners 124 a & 124 b further secures the webbing 120 to the frame 110.

Webbing 120 can also include an opening 127 thereby creating an optional window for accommodating snowshoe binding 130 with optional spikes and/or shoes (not shown) that may be configured with crampons to provide additional traction in packed snow commonly found in well-travelled trails or on icy trails. Webbing 120 can be made from one or more of a wide variety of natural, synthetic and/or blended materials including nylon, neoprene, Kevlar, and animal hides.

Referring now to FIGS. 2A & 2B, frame 110 is now described in greater detail. Frame 110 includes end caps 224 a & 224 b, front bars 219 a & 219 b, joint extensions 217 a & 217 b, joints 216 a & 216 b, center bar 215, rear bar pairs 214 a & 212 a and 214 a & 212 b, and end caps 222 a & 222 b. FIG. 2C illustrates how collapsible frame 110 can be compactly folded for ease of travel, e.g., for backpacking.

Front bars 217 a, 217 b can be removably coupled to joints 216 a, 216 b, via elastic cords 218 a, 218 b attached to end caps 224 a & 224 b and through joint extensions 217 a, 217 b, respectively. In addition, rear bar pairs 214 a & 212 a can be removably coupled to joint 216 a via elastic cord 213 a attached to end cap 222 a. Similarly, rear bar pairs 214 b & 212 b can be removably coupled to joint 216 b via elastic cord 213 b attached to end cap 222 b.

FIGS. 3A & 3B and FIGS. 4A & 4B illustrate additional alternate collapsibility configurations between joints 216 a & 216 b and respective bars 214 a, 214 b & 215. For example, in FIGS. 4A & 4B, center bar 215 is detachable coupled to joints 216 a, 216 b via elastic cord 415.

Note that in the various described embodiments, elastic cords, e.g., cords 213 a, 213 b, 218 a, 218 b, and 415 can be a single cord or combination of several jointed cords. For example, cords 213 a and 218 a can be formed from a single continuous cord. It is also possible to combine several strands of thinner cords into a single stronger cord. Elastic cords of frame 110 can be made from a suitable strong and stretchable material such as rubber or Bungee.

The bars forming exemplary frame 110 of the described embodiments function to support webbing 120 and hence the weight of a user. Accordingly, the bars can be one of several suitable variations. In most embodiments, the bars are cylindrical rods, but may alternatively have any suitable geometry and may have varying geometries along the length of the rods. The bars are straight or linear bars, but may alternatively be curved, bent, or have any other suitable geometry. The bars can be made of metal (such as 0.433″ 7075 T9 aluminum poles with approximately 0.030″ wall thickness), or plastic, but may be alternatively made from any suitable material, such as titanium, carbon fiber and/or fiberglass. The bars are collapsible or foldable such that they include multiple sections that can be assembled to support the sling and the weight of the user and can be disassembled for easy transportation and storage. Each of the sections are straight, but may alternatively be curved or angled. Each section may have the same radius of curvature or angle, but alternatively each section may have a different radius of curvature or angle.

FIG. 9 further illustrates collapsible bars for exemplary frame 110, with each collapsible bar including two or more bar sections. In some embodiments, collapsible bar 900 includes a first bar section 930 and a second bar section 932 removably coupled to the first bar section 930. The first bar section 930 has an end portion with an outer diameter dimension 984 and the second bar section 932 has an end portion that defines a recess 936 that receives the outer diameter dimension 984 of the end portion of the first bar section 930. The outer diameter dimension 984 has a diameter less than the outer diameter of the collapsible bar 900. For example, the bar 932 may have approximately 0.370″ outer diameter while the bar 930 has an outer diameter 984 of approximately 0.433″. The end portion of the first bar section 930 may be a separate piece that is coupled to the first bar section 930. For example, the separate piece may have an outer diameter of approximately 0.433″ with approximately 0.040″ wall thickness. Alternatively, the first bar section may couple to the second bar section in any other suitable fashion. The first bar section 930 is substantially identical to the second bar section 932, but alternatively, the first bar section 930 and the second bar section 932 may have different geometries, dimensions, and/or cross sections.

II. Assembly of Collapsible Snowshoe Embodiments

IV. Additions to and Modifications of Collapsible Snowshoes

Many additions and modifications to the exemplary embodiments described above are also contemplated within the scope of the present invention. For example, buckle sets 124 a, 124 b and 1124 a, 1124 b can be replaced by hook and loop interfaces. Strap 122 may be made from an elastic material.

In addition, center bar 215 may be secured to joints 216 a, 216 b without an internal elastic cord. Instead, an optional pair of corresponding ball-and-detent couplers, twist-lock couplers or threaded couplers may be incorporated at the respective ends of center bar 215 (not shown).

As shown in the top and side views of FIGS. 15A and 15B, snowshoe 1500 may include optional retractable crampon 1580 operatively coupled to center bar 1515. FIGS. 15A and 15B illustrate rotatable crampon 1580 secured in a retracted mode and a deployed mode, respectively.

In the above described exemplary embodiments, the joints, e.g., joint 216 a & 216 b can include openings configured to retain exemplary bars and bar sections, e.g., bars 219 a, 219 b & 215 and bar sections 214 a & 214 b. Accordingly, in some embodiments, joints of frames, e.g., frame 110, may include circular and/or non-circular recesses configured to retain a portable chair cross member (see exemplary joint 1000 of FIG. 10). Non-circular recesses enhance stability by reducing twisting motions between the respective joint and cross member in the assembled state. Many non-circular recess profiles are possible, such as elliptical, polygonal (including quadrilaterals such as rectangular, rhombus, trapezoid), and triangular. Hence, exemplary twist-resistant joint geometries for joints for snowshoe frames include ovals (e.g., joint 1000), hexagons, D-shapes, triangles, rectangles and squares.

Further, frames for snowshoes can be secured to their respective webbings using suitable alternate mechanisms, for example, using hook and loop interfaces instead of stitched sleeves. In addition, selected portions of webbings, e.g. webbing 120, can be substantially contiguous and/or substantially perforated.
